9.0 REVIEW, MODIFY AND DELETE

Press MODE to advance to any of the following MODES:

1. AUTO MODE: In this automatic mode, the unit will execute the scheduled programs. Time, day, seconds and load status are displayed. If today is a programmed holiday, the day of the week will ﬂash.

OVERRIDE IN AUTO MODE: The load status of the channel can be manually changed by pressing the OVRD key (or OVR1 and OVR2 key for two channel

units). The unit will stay in this position until the next scheduled event. A ﬂashing LCD load indication (ON, OFF) shows the status was changed by the override not a scheduled event.

Note: To force the circuit ON when an EPC-A photo sensor installed, you must cover the photo sensor and place the override into the ON position.

2. MAN MODE: In this manual mode, the unit will ignore the schedule programs. Time, day, seconds and load status are displayed. If today is a programmed holiday, the day of the week will ﬂash. This can be used as a VACATION SETTING to keep load off while away. Use override to set to OFF position.

OVERRIDE IN MAN MODE: The load status of the channel can be manually changed by pressing the OVRD key (or OVR1 and OVR2 key for two channel

units). The unit will stay in this position until OVRD is pressed again. A ﬂashing LCD load indication (ON, OFF) shows the status was changed by the override not a scheduled event.

3. CLOCK MODE: Press HOUR and MIN to modify

existing settings. Press ENTER to save changes.

4. DATE MODE: Press MONTH, DATE and YEAR to modify existing settings. Press ENTER to save changes. DAY is automatically adjusted.

5. DSt MODE: Factory default is set at US standard daylight savings dates noted by ON. To remove daylight savings time setting, press DEL to change screen to show OFF. DST may be activated again by pressing DEL. Press ENTER to save changes. To change from the standard DST month/ week/day setting press HOUR and refer to step 4.1.

6. HOLIDAY MODE: Press ENTER to advance to desired holiday. Press MONTH and DATE to modify start of holiday (ON) then press ENTER. Press MONTH and DATE to modify end of holiday (OFF) then press ENTER to save changes.

7. SCH MODE: To change schedule, press ENTER to advance to desired event. Press HOUR, MIN, EVENT, and DAY to modify time settings. Press DEL to delete. Press ENTER after each modiﬁcation to save changes.

NOTES:

1. Unit has a look back feature. Press the EVENT key once (or twice for two circuit units) to activate current schedule then EVENT key again to return to the time (run) screen. Unit will automatically pick up the last schedule.

2. To clear date and time only and provide unit with a soft reboot, press and release the reset button that is recessed under the small hole to right side of LCD screen.

3. Clear all memory. To clear all memory, while in the RUN mode, press ENTER, display will show:

Use the EVENT key to display:

Now Press ENTER brieﬂy and everything in the timer

memory is cleared and 12HOUR will ﬂash.

4. A “PF” on the display indicates a Power Failure and the unit requires AC power to operate. The time and date are protected for 7 days by the super cap. The program is retained in permanent memory.

5. A “Lo” on the display indicates that the super cap has run low and the unit needs to be powered with AC. A minimum of 8 hours is required to fully charge the super cap.

Planning Your Program The single channel unit will operate as a standard timer for typical indoor or outdoor control needs. Only

if a photo sensor is connected can it operate with a photo and time logic.

Two channel units allow you to set-up different control logic for each channel by using the Select Switch. To meet Title 24 requirements, one channel could be sunset to sunrise while the other channel is sunset to time OFF. Also one channel could be used for indoor lighting control with ﬁxed ON and OFF times while the other channel is set for sunset to sunrise.

The photo sensor will only operate when the program is set to ON. Here are examples for the most common uses. For other ideas call the toll free Tork Tech Help Line 888-500-4598.

1. Sunset ON and Sunrise OFF 7 days a week: Program the channel for an ON event at 12:00am Monday through Sunday. The photo sensor will take full control and turn on the load ON only when light level drops to the preset footcandles then turns OFF

when the light level is twice the preset footcandles. (For two channel units also set select switch to PHOTO setting.)

2. Sunset ON and Time OFF: Program an ON event at the earliest time you want to allow photo sensor to begin to operate. Then program a night time OFF event. (For two channel units also set select switch to PHOTO setting.)

Example: ON at 3:00pm and OFF at 11:00pm MO – SU. The photo sensor will take control at 3:00pm and turn ON the load only when light level drops to the preset footcandles, but timer will shut OFF the load at 11:00pm regardless of the light level at that time.

3. Time ON and Time OFF: Program the channel for an ON event and an OFF event for the times you choose. Do not connect a photo sensor. (For two channel units photo sensor may be connected but also set select switch to TIMER setting.)

Timed Override

Wiring a Tork SS410 to the remote override connections provides an easy way to meet various energy code requirements for indoor lighting. Include the Tork #TRP to power the low voltage switch.

A Tork A502H may also be used to provide a low cost 2 hour override.

INPUT CONNECTIONS

There are two removable terminal blocks on the rear of the units. The terminal blocks, as viewed from the rear, are labeled TB3 (left side, green), and TB2 (right side,

black).

TB3 is used to connect the EPC-A to the unit. Wire the terminal block from left to right, with the blue, black, and red wires going to the EPC-A, wire length not to

exceed the length shown in the chart above. Calibrate per instructions below. The other terminal block, TB2 is used as remote override inputs. Three wires are used: common wire, channel 2 (if DGLC200A), and channel 1.

NOTE: Do not use any supply voltage for these wires. They should only be connected to dry (unpowered) switches. Closing contacts between the wires for channel 1 and common together will turn load 1 ON. Load will stay ON as long as the two wires are connected, no matter what the timer is set for, or the light level. Closing contacts between the wires for channel 2 and common together will turn load 2 ON. The load status change due to remote override will not be shown in the display.

Photo Sensor Calibration After installation, in order to ensure accurate light level performance, completely cover the EPC-A sensor. Then gently press the recessed Sensor CAL Switch for at least 5 seconds. After this button has been pressed, the red LED directly above the button will blink four times. If the button is pressed accidentally when the light level is above 10 foot candles, the unit will not recalibrate and the LED will blink once to signal that it did not change calibration.

The Light Level dial adjusts the foot-candle (fc) set

is for timer function only

point for the control to turn ON. The load will be turned OFF and continue to hold OFF when the light level is twice this level or more. A timer program must be active for the light level feature to function see “Planning Your Program” below.

The Time Delay dial adjusts the amount of time before the load turns ON or OFF due to light level change. The range is between 1 and 100 seconds. To prevent short-duration events such as clouds or stray lighting from prematurely turning the load ON or OFF, select longer time durations.
